Why can't I use module in python imported as alias in another import statement?

Question

Why do I get a ModuleNotFoundError: No module named 'tf' for:

import tensorflow as tf
import tf.keras.models

doesn't Python reference tf as an alias to tensorflow from the line import tensorflow as tf?

When you do

import tensorflow as tf

it has already imported all the sub-modules as tensorflow is a package.

So, to get the models, you just need to access it, no need to import

tf.keras.models

If you wanna import a specific module, then,

from tensorflow.keras import models

Are you sure? according to https://stackoverflow.com/questions/49641621/do-i-need-to-import-submodules-directly , I should import each submodule explicitly. – Benny K Oct 15 '19 at 09:33

You need to import specific submodule explicitly if you only use that submodule. – Vishnudev Krishnadas Oct 15 '19 at 09:51

Try using with tensorflow

import tensorflow as tf
import tensorflow.keras.models

Or you can use it as

import tensorflow as tf
sys.modules['tf'] = tensorflow
import tf.keras.models
